CHISHOLM ROBERT LUNDY, OF WINNIPEG, MANITOBA, CANADA.

VAPCRIZING ATTACHMENT.

To all w lzmn z't may concern;

Be it known that I, CHIS'HOLM ROBERT LUNDY, of the city of Winnipeg, in the Province of Manitoba, Canada, have 1n-' vented certain new and useful Improvements in vaporizing Attachments, of which the following is the specification.

The invention relates to vaporizing attachments, particularly as applied on automobile engmes, and the objectof the invention'is to provide a simply constructed, du- .rable and ethclent vaporizer whlch can be readily attached to the intake manifold of an engine and which Willsupply hot air to the intake manifold to mix with and more effectively vaporize the firing mixture passing to the cylinders.

- A further object is to construct the appliance so that the hot air admitted by the vaporizer will be drawn into the intake manifold in jets which will effectively insure of the intimate mixing of the admitted hot air with the up-going charge.

A further object is to construct the vaporizer so that a part of it will fit a portion of the exhaust manifold and form with the manifold an air pocket/utilized as a sourceof' hot air forthe vaporizer.

- With the above objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointedout in the appended claims, reference being had to the accompanying drawing in which: I Y

Figure 1 represents a side view of an engine-with my device applied thereon.

Fig. '2 represents an enlarged detailed side view of the vaporizer as it appears associated with the exhaust and intake manifolds.

Fig. 3 represents a side view of the I Specification of Letters Patent.

mobile engine, 2 the intake manifold and 3 the exhaust manifold, which parts are'fall of ordinary construction and are not herein further explained.

The vaporizer which I supply is attached to the intake manifold and has a part fitting the exhaust manifold and is constructed in detail as now described.

4 represents a nipple having one end thereof screw threaded into the 'intake manifold and the other end thereof formed into a valve casing 5 which is supplied with any suitable form of controlling valve. 6.

7 represents the passage or duct passing through the nipple and which communicates in the ordinary way with the interior of the valve casin The end of the nipple adjoining the intake manifold is flared and in the flared end I insert and secure a coneshaped member 8 which is provided with a plurality of inlet orifices 9 which converge toward the duct and are arranged to admit and spread the air entering the manifold from the passage 7.

10 represents a feed pipe connected by means of an elbow 11 with the nipple, thearrangement being such that the valve controls the passage of the air from the feed pipe to the manifold. To the upper end of the feed pipe I secure an open sided U- shaped collector 12 which has one end closed at 13 and the other end open as indicated at 14 and is shaped to snugly fit the exhaust manifold whereby an air pocket 15 is provided, the air pocket having the front end closed by the wall 13 and the rear end open.

With this article applied on the engine and the engine working it will be obvious that the air in the pocket'1,5 will become.

very hot, due to the heat radiated from the exhaust manifold and further it will be apparent that the air in the pocket will not be disturbed owing to the fact that the front end is closed. The hot air in the pocket is drawn down the pipe 10 and through the nipple to the intake manifold on the suction stroke of the engine and is what might be termed sprayed into the manifold through the orifices 9.

By admitting the hot air into the intake manifold in this way I secure a veryintimate mixing of the hot air with the upgoing charge and effect a more complete and in actual practice an operatin 7 could be connected to the valve so tiat it could be conveniently controlled by the vaporization of the charge and consequently Thevalve can be regulated as required to control the supply of hot air to them anifold driver. This is such a simple and obvious expedient that details of it have not been shown. e

- WVhat' I claim as my invention is r 1. The combination with the intake and exhaust manifplds of an engine, of an air collector secured to the side and extendin lengthwise of the exhaust manifold and having the front end closed and the rear end open, a pipe leading from the side of the collector downwardly to the intake manifold, a nipple connecting the pipe with the intake mapifold opening to the inter'ior of the intake manifold, a valve controlling passage vthrough the nipple and a link 'exhaustmanifolds of an engine, of an open sided substantially 'U-shaped metallic collector extending lengthwise of the manifold and having the open side fitting the man-L fold, the said collector having the front end closed'and the rear end open,"a pipe leading. Q

from the outer side of the collector down- 'ward1y to the intake manifold 'and a connection between the lower .end of the pipe and the, interior of the intakemanifold, said connection embodying controlling valve.

and a -s reading jet, the jet being at the manifol end'of the said latter connection;
